Definitions

  • the present invention relates to the field of radiotelephone communications and more particularly to methods of transmitting and receiving incoming call pages in radiotelephone communications systems.
  • a radio link between a mobile user terminal and the radiotelephone communications system can be used to support communications between the mobile user terminal and a second mobile user terminal, or between the mobile user terminal and a telephone on the wired communications system.
  • the radiotelephone communications system When a call is placed to the mobile user terminal, the radiotelephone communications system sends an incoming call page to the mobile user terminal over a control channel indicating the presence of an incoming call. Upon reception of this incoming call page by the mobile user terminal over the control channel, the user terminal and the radiotelephone communications system initiate a series of control communications to establish a link therebetween over a dedicated channel.
  • the Asia Cellular Satellite (AceS) proposed by Lockheed Martin Corporation and Ericsson Mobile Communications AB provides that a sequence of up to 5 incoming call pages be transmitted by the satellite system in indication of an incoming call.
  • a predetermined uniform delay is provided between each of the incoming call pages of the sequence and a period of time (longer than the predetermined uniform delay) is provided after the last page of the sequence within which the user can respond to the incoming call to establish a radiotelephone communications link.
  • a sequence of multiple incoming call pages may be sent. Furthermore, one or more of the sequence of incoming call pages may be sent at an increased power level (such as over a High Power Alert Channel) to increase the probability of being received by the mobile user terminal. Accordingly, the mobile user terminal can respond to the incoming call any time between the first and last pages of the sequence of pages as well as within the predetermined period of time provided after the last page of the sequence.
  • This and other objects are provided according to the present invention by including information in the incoming call pages which allows the receiving user terminal to determine a period of time available for response if communications cannot be established immediately. An indication of this period of time can then be provided to the user who is able to decide if there is sufficient time to try to move to a location which will allow communications to be established.
  • the mobile user terminal may be in a building when a high power incoming call page is received and may be unable to respond immediately because of interference due to the building. By moving outside within the period of time allowed for response, however, the mobile user terminal can respond to the incoming call. The frustration of moving outside the building to only then learn that the time for response has elapsed can thus be reduced.
  • one or more of the pages in a sequence can be missed without shortening the period allowed for response.
  • the incoming call page from the radiotelephone communications system is received at the mobile user terminal.
  • the period of time within which the mobile user terminal can respond to the incoming call is then determined, and an indication of this period of time is provided to the user.
  • the incoming call page can be one of a predetermined number of incoming call pages addressed to the mobile user terminal in a sequence wherein each of the incoming call pages in the sequence includes information identifying the respective incoming call page within the sequence.
  • the step of determining a period of time within which the mobile user terminal can respond to the incoming call can include determining the number of incoming call pages in the sequence to follow.
  • the information identifying the respective incoming call page within the sequence can include a number that is incremented or decremented for each successive incoming call page in the sequence.
  • the mobile user terminal can receive timing information including a time duration between each of the incoming call pages in a sequence and including a predetermined period of time after a last of the incoming call pages in a sequence within which the mobile user terminal can respond to the incoming call.
  • the timing information can be received as a portion of each of the incoming call pages, the timing information can be received over a control channel independent of the incoming call pages, and/or the timing information cab be programmed into mobile user terminal memory.
  • the timing information is received over a control channel independent of the incoming call pages.
  • a radiotelephone communications system determines that there is an incoming call for the mobile user terminal, and transmits a predetermined number of incoming call pages addressed to the mobile user terminal in a sequence.
  • Each of the incoming call pages in the sequence includes information allowing the user terminal to determine a period of time within which the mobile user terminal can respond to the incoming call. Accordingly, the mobile user terminal can determine the period of time available for response to the incoming call and provide this information to the user.
  • Methods, terminals, and systems according to the present invention thus allow the recipient of an incoming call to make an informed decision as to whether there is enough time to move from a location providing disadvantaged communications to a location providing advantaged communications in response to an incoming call. User frustration can thus be reduced.

  • a radiotelephone communications system can be implemented as a satellite communications system including at least one satellite 21 and a terrestrial controller 23 which can be coupled to a wireless communications system such as a Public Land Mobile Network (PLMN) 26 , and/or to a wired communications system such as a Public Switched Telephone Network (PSTN) 25 .
  • PLMN Public Land Mobile Network
  • PSTN Public Switched Telephone Network
  • the terrestrial controller 23 and the satellite 21 are coupled through radio links 27 .
  • the satellite 21 and at least one user terminal 29 can be coupled through radio links 31 .
  • the satellite communications system can provide communications to and from a plurality of user terminals, and the satellite can provide service through a plurality of spot beams (or cells) each covering a different geographic region.
  • the satellite communications system can include a plurality of satellites and/or a plurality of controllers. Accordingly, the satellite communications system can facilitate communications between the mobile user terminal 29 and another mobile user terminal, or between the mobile user terminal 29 and a telephone coupled to the public switched telephone network.
  • the user terminal can be a radiotelephone, a portable computer, a personal digital assistant, or any other electronic device adapted for radiotelephone communications.
  • the communications system may establish a radiotelephone communications link with the user terminal 29 using a traffic channel via a radio link 31 .
  • a link can be established responsive to a call placed by a telephone from the PSTN 25 , or the link can be established responsive to a call from another user terminal coupled to the satellite 21 or coupled to another satellite in the communications system.
  • the link can be established by transmitting an incoming call page from a transceiver of the satellite 21 wherein the incoming call page is transmitted at a first power level.
  • the incoming call page may be transmitted over a control channel.
  • the user terminal 29 acknowledges receipt thereof and a two-way radiotelephone communications link is established over a dedicated channel such as a traffic channel.
  • the user terminal can respond to establish a radiotelephone communications link any time between the transmission of the first incoming call page of the sequence and a predetermined period of time after the transmission of the last incoming call page of the sequence. Otherwise, the communications system may assume that the user terminal 29 is not available and terminate the incoming call.
  • This situation is referred to as a disadvantaged communications situation and may occur, for example, when the user terminal is in a building.
  • a radiotelephone communications link can be established, however, if the user terminal can be moved to a location providing advantaged communications, such as by moving the user terminal outside the building, within the period of time allowed by the communications system for response.
  • Communications systems and methods according to the present invention facilitate this situation by providing information in each of the incoming call pages which identifies the respective incoming call page within the sequence.
  • each incoming call page can indicate how many subsequent pages are to follow in the sequence.
  • the user terminal can use this information to determine how much time is available for the user terminal to respond to the incoming call page and establish a radiotelephone communications link, and the user terminal can provide an indication of this time to the user through a user interface either visually or audibly.
  • the indication of the time can be provided using a countdown on a digital or analog display, using an audible countdown, using a countdown on a graphical display, etc.
  • a predetermined number of incoming call pages can be generated in each sequence, and each incoming call page in a sequence can include a field indicating the number of incoming call pages in the sequence to follow.
  • a field indicating the number of incoming call pages in the sequence to follow.
  • five incoming call pages can be included in a sequence, and the field (such as a counter value) indicating the number of subsequent pages can be 4, 3, 2, 1, and 0 for the respective incoming call pages in the sequence.
  • the number of incoming call pages in a sequence, the time duration between each of the incoming call pages in a sequence, and the period of time after the last call page within which a response from the user terminal will be accepted are system parameters that can be provided to the user terminal. Accordingly, the user terminal can use this information together with the number of subsequent pages to determine the total period of time within which the user terminal can respond to the incoming call to establish a radiotelephone communications link. This period of time can be provided through a user interface to the user of the user terminal who can then decide if there is enough time to move to a location providing advantaged communications. Accordingly, the frustration of moving to a location providing advantaged communications only to learn that the time allowed for response has expired can be reduced.
  • the communications system parameters including the number of incoming call pages in a sequence, the time duration between each of the incoming call pages, and the time period after the last page in a sequence during which a response will be accepted can be saved in user terminal memory.
  • These system parameters can be programmed into the user terminal memory when a service account is established for the user terminal, or these system parameters can be transmitted by the communications system such as over a control channel. Alternately, some or all of these parameters can be provided to the user terminal as part of the incoming call pages. By transmitting these parameters, system changes can be accomplished without reprogramming user terminals.
  • FIG. 2 A block diagram of a user terminal according to the present invention is illustrated in FIG. 2 .
  • the user terminal includes a transceiver 41 which receives radiotelephone communications from the communications system at the first power level and which transmits communications to the communications system as is known.
  • the transceiver can also receive incoming call pages from the communications system at a second power level higher than the normal power level. Accordingly, the transceiver 41 can receive incoming call pages from the radiotelephone communications system at both normal and high power levels. In particular, high power level incoming call pages can be received over a high power alert channel.
  • a processor 43 is coupled to the transceiver 41 so that the processor can process communications transmitted and received by the transceiver. More particularly, the processor can process any incoming call pages addressed to the user terminal and generate a notification signal such as a ringing through the user interface 45 to notify the user that there is an incoming call. If the user terminal is in a location providing advantaged communications, such as outside, the user terminal can respond immediately to establish a two way radiocommunications link. If, however, the user terminal is in a location providing disadvantaged communications, such as inside a building, the processor can determine a period of time within which the user terminal can respond to the incoming call and provide this time to the user through the user interface 45 .
  • the user interface 45 is coupled to the processor 43 , and the user interface can include a keypad 45 A; a visual display 45 B such as a liquid crystal display (LCD), a light emitting diode (LED) display, and/or an alpha-numeric display; a microphone 45 C; and a speaker 45 D. More particularly, the user interface 45 can provide notification to the user that an incoming call page has been received and as well as the period of time within which the user terminal can respond to the incoming call page. For example, the period of time for response can be provided audibly using the speaker 45 D or other audio generating means, or visually using display 45 B. The time itself does not need to be provided. Alternatively, an indication of the time can be provided, for example, using a graphical display.
  • a graphical display such as a liquid crystal display (LCD), a light emitting diode (LED) display, and/or an alpha-numeric display
  • the user interface 45 can provide notification to the user that an incoming call page has been received and
  • the user terminal can also include a memory 47 coupled with the processor 43 .
  • the memory 47 can be used to store timing information relating to the sequence of the incoming call pages.
  • the memory 47 can be used to store time durations between incoming call pages within a sequence, as well as a predetermined period of time after the last page of a sequence within which the user terminal can respond to establish a radiotelephone communications link.
  • the processor 43 can thus use information from a received incoming call page together with the timing information stored in memory 47 to determine the period of time within which the user terminal can respond to the incoming call. Moreover, this determination can be made even when only one incoming call page of a sequence is received because the received incoming call page includes information indicating how many subsequent pages of the sequence are to follow.
  • FIG. 2 may be provided by hardware, software, or a combination of the above. While various components of the apparatus of the present invention have been illustrated in part as discrete elements in the FIG., they may, in practice, be implemented by a microcontroller including input and output ports and running software code, by custom or hybrid chips, by discrete components or by a combination of the above.
  • the memory 47 and the processor 43 may be implemented as a segment of existing memory and additional code executing on an existing processor of the user terminal respectively.
  • a radiotelephone communications system waits at block 101 until an incoming call is detected for a user terminal 29 at block 103 .
  • a sequence counter is set to an initial value at block 105 .
  • the sequence counter can be initially set to a number equal to one less than the number of incoming call pages transmitted in a sequence in response to an incoming call.
  • the counter value transmitted with each incoming call page in a sequence will indicate the number of incoming call pages to follow in the sequence.
  • the Asia Cellular Satellite System Air Interface Specification currently provides three unused bits in the data format for the incoming call page, and these bits can be used to accommodate the transmission of the counter value.
  • the first incoming call page including the counter value at the initial value is transmitted at block 107 , and if no response is received from the user terminal at block 111 , the counter value is checked to against the final counter value at block 113 . In addition, a delay for a predetermined period of time is provided at block 109 between each of the incoming call pages transmitted in the sequence. If the counter value is not equal to the final value at block 113 , the counter value is decremented at block 117 before the transmission of the next incoming call page in the sequence with the decremented counter value at block 107 . This loop continues until either a response is received from the user terminal 29 being paged at block 111 , or until all incoming call pages of the sequence have been sent without response from the user terminal as determined at block 113 .
  • a radiotelephone communications link is established at block 119 .
  • the radiotelephone communications link is terminated as block 121 , and operations go back to the wait operation at block 101 .
  • the period of time for the delay at block 109 can be the same or vary between each of incoming call pages in a sequence.
  • the delay at block 109 also provides a period of time after the last incoming call page of a sequence within which the user terminal can respond to establish a radiotelephone communications link. This final delay can be the same as or different from the preceding delays.
  • each of the delays between pages in a sequence can be the same, and the period for response after the last page can be longer than the delay between pages.
  • the delays of block 109 can be configured so that information including the duration of one delay can be used by the user terminal to determine all of the delays. For example, predetermined correlations between the delays can be provided so that only one delay duration needs to be provided to the user terminal in order for the user terminal to determine all of the delays.
  • the user terminal can use the counter value transmitted with any of the incoming call pages to determine how many subsequent pages in the sequence will follow, and how much time is available to respond to the incoming call to establish a radiotelephone communications link through the radiotelephone communications system. More particularly, the user terminal 29 can use the counter value transmitted with an incoming call page together with the delays between each page in a sequence and the period of time after the last page in a sequence to determine the time available for a response. By providing an indication of the time available for a response to the user, the user can decide if there is sufficient time to move from a disadvantaged communications location to an advantaged communications location to receive the call.
  • the duration of each delay between pages of a sequence, and/or the duration of the period of time after the last page within which the user terminal can respond can be transmitted by the radiotelephone communications system.
  • This information can be transmitted as part of each incoming call page or over a control channel independent of the incoming call pages. Alternately, this information can be programmed in user terminal 29 memory 47 .
  • the user terminal 29 waits at block 201 until an incoming call page is received from the radiotelephone communications system at block 203 .
  • the user terminal 29 determines whether a two way radiotelephone communications link can be established immediately at block 205 . If the user terminal is in a location providing advantaged communications, such as outside with a relatively unobstructed radio path to the communications system, the user terminal can inform the user of the incoming call and respond immediately to the incoming call page at block 207 . Accordingly, a two-way radiotelephone communications link can be established with the communications system at block 209 to support a radiotelephone call. When the call is completed, the radiotelephone communications link can be terminated at block 211 , and the user terminal 29 again waits at blocks 201 and 203 for the next incoming call page.
  • the user terminal 29 may be unable to establish communications immediately with the radiotelephone communications system at block 205 .
  • the user terminal 29 may be located in a location providing only disadvantaged communications, such as in a building, so that an obstructed radio path is provided between the user terminal and the radiotelephone communications system.
  • the communications system can generate a sequence of incoming call pages responsive to an incoming call, and one or more of these pages may be transmitted at a relatively high power such as over a high power alert channel (HPACH).
  • HPACH high power alert channel
  • the user terminal 29 When in a location providing disadvantaged communications, the user terminal 29 may be unable to receive an incoming call page transmitted at a normal power level, and the user terminal 29 may be unable to send transmissions to the communications system.
  • the user terminal 29 may, however, be able to receive an incoming call page transmitted at a relative high power, such as over a high power communications channel.
  • the user terminal 29 can use information from the page to determine the period of time available to respond to the incoming call at block 213 .
  • An indication of the period of time can be provided to the user through the user interface 45 at block 215 .

If the user terminal 29 is moved to the position providing advantaged communications within the period of time allowed for response so that communications can be established at block 217 , a response is transmitted to the radiotelephone communications system at block 207 , and a radiotelephone communications link is established at block 209 to support a radiotelephone call. When the radiotelephone call is completed, the radiotelephone communications link is terminated at block 211 , and the user terminal waits for the next incoming call page at blocks 201 and 203 .
  • the user terminal 29 is provided with information including the number of pages in an incoming call page sequence, the duration of the delays between each page in the sequence, and the period of time after the last page in a sequence within which the user terminal can respond to an incoming call.
  • This information can be provided by the radiotelephone communications system as a portion of each of the incoming call pages, or this information can be provide by the radiotelephone communications independently of the incoming call pages. For example, this information can be transmitted over a control channel and stored in user terminal memory. Alternately, this information can be programmed into user terminal memory when a service account with the radiotelephone communications system is established for the user terminal or a combination of these two methods can be used. Accordingly, this information can be used together with the counter value included in the incoming call pages to determine a period of time available for the user terminal to respond to the incoming call.

  • the period of time after the last page within which the user terminal can respond is 1 minute.
  • the user terminal is positioned at a disadvantaged location so that only the third incoming call page of the sequence transmitted over the high power alert channel is received by the user terminal.
  • the user terminal processor can multiply the duration of the delay between pages (20 seconds) by two and add the period of time after the last page within which the user terminal can respond (1 minute) to determine that the user has 1 minute and 40 seconds to move to a location providing advantaged communications and respond to the incoming call.
  • the user terminal can provide an indication of this period of time to the user through a user interface such as a liquid crystal display. The user terminal can further load this time period into a timer and provide a countdown to the user through the liquid crystal display.
